HIQ PDF -Konvertierungsproblem: Körpertext überlappen sich mit Kopfzeile und Fußzeile ⇐ C#

[Anonymous]

Ich verwende Hiq PDF, um meinen HTML -Inhalt in ein PDF -Dokument umzuwandeln. Gelegentlich begegne ich ein Problem, bei dem sich der Körpertext mit der Kopfzeile und der Fußzeile überlappt. Dieses Problem tritt nicht jedes Mal auf, passiert aber sporadisch. Unten ist der Code, den ich benutze.

Code: Select all

@model MyProjectLibrary.Model.PatientLetter[b]
@{
Layout = "~/Views/Shared/_LayoutPopup.cshtml";
}

body {
background-color: #FFF !important;
color: black !important;
font-size: 14px !important;
}

u {
font-size: 22px !important;
}

@if (Model.LetterType != "Blank")
{
if (Model.LetterType == "Diagnosis Confirmation")
{


[u]To Whom It May Concern,[/u]


}
else if (Model.LetterType == "GP")
{


[u] CONFIDENTIAL[/u]


}


DATE:[/b]@Html.Raw(Model.AppointmentDateStr)[b]



Re:[/b]@Html.Raw(Model.modelPatient.FirstName) @Html.Raw(Model.modelPatient.SurName)[b]



DOB:[/b]@Html.Raw(Model.modelPatient.DateOfBirthDateOnly)[b]

if (Model.LetterType == "GP")
{


Dear Dr:[/b]@Html.Raw(Model.modelPatient.modelGPPractice?.Name)[b]

}
}
else
{


DATE:[/b]@Html.Raw(Model.AppointmentDateStr)


}


@Html.Raw(Model.LetterBody)

Problem: Der Körpertext überlappt sich manchmal mit der Header und der Fußzeile im erzeugten PDF. Hat jemand auf ein ähnliches Problem gestoßen, und wenn ja, wie haben Sie es gelöst? > Was ich ausprobiert habe: < /strong> < /p>

• Einstellen der Header- und Fußzeilenhöhen. Werte.

Ich muss das Problem des Körpertextes einiger Zeit mit der Header/Fußzeile lösen.
